How we picked theseFinder Score - Home insurance
We crunch eligible home insurance products in Australia to see how they stack up. We rank over 50 products on 16 different features, including price. We end up with a single score out of 10 that helps you compare home insurance a bit faster. We assess home and contents, building only and contents only products individually.
Determining the best building insurance requires looking beyond just the monthly premium. At Finder, we use a rigorous methodology to identify top performers through our annual Finder Awards, which recognise insurers that excel in areas such as value, coverage and customer service. The Customer Satisfaction Award is based on direct feedback from thousands of Australian policyholders, focusing on transparency and ease of communication. You can find more detail on how we calculate these scores in our methodology pages, which help build an authoritative ranking guide reflecting the reality of policyholder experiences

How much cover do I need?
Having the right level of protection in place can save you thousands of dollars in the long run. However, some estimates suggest that as many as 80% of Aussie's are under-insured. Whilst it may seem appealing to cut costs at first, the risk of not having enough cover in place is not worth it.
The building insurance policy you take out should cover the total replacement cost of your property, including other expenses which may arise such as demolition and temporary accommodation. If you're under-insured, you'll have to pay the gap between what your policy covers and the replacement cost for your building, which in many cases could be a substantial amount of money.
To help calculate the cost of what it'd cost to replace your home, you can use a building insurance calculator. While these aren't perfect, it's a good starting point.
